AARON S. PENNINGTON, OF PATERSON, NEW JERSEY.

IMPROVEMENT IN COMBINED POCKET-KNIVES AND ENVELOPE-OPENERS.

Specification forming part of Letters Patent No. 122,960, dated January 23, 1872.

Specification describing a certain Improvement in Combined Envelope-Opener and Pocket-Knife invented by AARON S. PENNINGTON, of Paterson, in the county of Passaic and State of New Jersey.

Figure 1 represents a side view, partly in section, of my combined knife and envelopeopener. Fig. 2 is a transverse section of same on the line 0 0, Fig. 1.

Similar letters of reference indicate corresponding parts.

This invention consists in forming a notch in the division-plate, between the several blades or springs of a pocket-knife, so as to convert such division-plate into an envelope-opener.

A in the drawing is the shell or frame of the pocket-knife. B B are the blades; 0 O, the springs for throwing and holding the blades opened or closed. D is the plate secured lengthwise in the shell or frame between the several blades or pairs of blades and springs.

The edge of this plate D has a notch, 11., formed in it, which produces apoint and cutting-edge, b, that can be used as an envelope-opener.

The plate D may be thus notched either between the blades or at the back of the knife, between the springs. In either case the combined knife and envelope-opener will constitute a convenient and desirable article of manufacture.

Having thus described my invention, I claim as new and desire to secure by Letters Patent A pocket-knife provided with a divisionplate, D, having a notch, a, forming a cuttingedge, substantially as shown and described, for the purpose specified.

A. S. PENNINGTON.
